Pof | Protein painting of fourth; Probable RNA-binding protein that specifically binds to the fourth chromosome and may bind an RNA that spreads the fourth chromosome. May be a reminiscence of X chromosome dosage compensation of ancestral Drosophila species in which the X and the fourth chromosomes are one single chromosome. (495 aa) | ||||
smg | Smaug (smg) encodes the founding member of the SMAUG family of sequence-specific RNA-binding proteins. During the maternal-to-zygotic transition in early embryos, the smg product inhibits the translation and induces the degradation of hundreds of maternal mRNAs by recruitment of the CCR4-NOT deadenylase complex, thereby controlling embryonic patterning, activation of zygotic transcription, and early embryonic cell cycles.
